Quantum technology

Nitrogen vacancy (NV)

Nitrogen vacancy (NV)

Diamond is a carbon crystal. If you remove a carbon atom in the crystal lattice and replace it with a nitrogen atom, this results in the creation of electron vacancies, hence the term “nitrogen vacancy.” Nitrogen-vacancy (NV) centers have the property of reacting very sensitively to changes in the surrounding environment and to changes in the quantum state, and this property can be used as a sensor function. For this reason, a diamond with an NV center is counted as a "quantum sensor" and is attracting attention as a next-generation ultra-sensitive sensor. Nitrogen vacancy is an attractive qubit modality for quantum computation and quantum simulation since it has the ability to operate at room temperature.

Recommended products

ORCA-Quest camera

The world's first camera to incorporate the qCMOS image sensor and to be able to resolve the number of photoelectrons using a newly developed dedicated technology.

ORCA-Fusion BT digital CMOS camera

The ORCA-Fusion BT digital CMOS camera enables quantitative detection of weak fluorescence from the NV center while maintaining high resolution.

LCOS-SLM (for research applications)

The LCOS-SLM is a reflective spatial light modulator that freely controls the phase of light with a liquid crystal. Precise wavefront control enables simultaneous multi-point irradiation.

MPPC modules

MPPC features high gain (about 106), high photon detection efficiency for detecting 650 nm NV fluorescence, wide dynamic range, and excellent photon peak value discrimination ability, so it can obtain high S/N for high-speed, weak signals. Available MPPC modules incorporate the MPPC, amplifier, and power supply, making them easy to use.
